    Abstract: 隨著電腦技術不斷演進,數位家庭的概念慢慢地得以實現,在以前無線網路還尚未實現之時,要完成無線媒體中心的概念,並不是一件容易達成的目標。現今無線網路的建置是輕而一舉的事,除此之外,我們還可以透過現有的2.5G或是3G網路來傳送資料,亦即可以透過2G或3G網路來上網,只要家電產品能夠內建GSM/GPRS/WCDMA或是802.11B/WiMAX這些無線模組。便可以透過上述不同的無線上網技術來取得IP。也由於所有家電產品的IP化,就可以進行通訊,進而達到遠端控制的目的,也提升軟體開發上的便利性。基於上述的環境,為了達成無線數位媒體家庭的目的,我們利用Intel公司所發展出來的UPnP開發工具,可以使得軟體開發者不需要熟悉UPnP的內部運作原理,便可以開發出運作在UPnP架構上的應用程式。 透過此工具,我們設計出一套無線數位媒體中心,此中心能夠讓使用者隨時隨地使用其他裝置分享影音資料。亦即透過其他裝置所提供的檔案,在其他不存在此檔案的裝置上,來播放這個影音資料,如此便可以達到資源共享的目的。也由於在無線網路的架構下,我們便能夠擺脫線的束縛,隨心所欲在任何地方,享受這些影音資料所帶來的聲光效果。並達成了零配置的目的,不需要做任何特別的設定便可以使用,免除增加使用者負擔的複雜設定,達成隨插即用的好處。 With the advances in computer technology, the Digital Home concept is being gradually realized. It is not easy to achieve the concept of wireless media center without wireless networks. Nowadays, the deployment of wireless networks is almost ubiquitous in our daily life. The data packets could be transferred via the 802.11 or 2.5G/3G technologies. These technologies can be applied to any consumer appliance embedded GSM/GPRS/WCDMA or 802.11B/WiMAX modules. Because all electrical appliances product can be IP to achieve the goal of communication, then may achieve the goal of the penetration far-end control, also facilitates in the convenience of software development. In order to realize the concept of Wireless Digital Home, we choose the Intel UPnP development kit as the development tool. It greatly helps to shorten development time because the developers are able to develop the UPnP applications without truly understanding UPnP working theory. Therefore, we utilize this tool to design a digital media system for users to be able to share media contents with other devices. Those devices without media contents are able to play the media contents from other devices via wireless networks. In wireless networks architecture, users are not constrained by the wired networks and are able to enjoy the great video/audio effects brought remotely from other devices with wireless networks. In addition to that, the goal of “Zero Configuration” can be realized. There is no specific setting required. The complexity setting could be reduced to minimum and achieved the advantage of plug and play.
